i To all whom imag concern.' i i 3 andDEXTER H. CHAMBERLAIN, both of Boston, in thecountyof `Suffolk and State `of Massachusetts, have invented a new and Improved Method of Hanging and Balanc-` ing Window-Curtains, of `which the followj i ing is a full, clear, and exact description, reference being had to the accompanying j drawings, in whichj `Figure lis a view of the curtainl with its fixtures;` Fig. 2,` an end view of the'same; Fig 3, a transverse section upon the curtain rod; Fig.4, alongitudinal section upon the lineA-,A, ofFig.` 2; Fig. 5, a view of'one ofthe adjustable sockets on Vwhich the` curtain revolves.` j i f l i `To enable others skilled in the art tomake luse of our finvention `we `will proceed to describe the `manner inwhich we have carried `it out. i

Y `Various "devices have been employed for "the purpose of balancing window curtains, y maps, &c., all of them Umore or less expensive and requiring care in theirmanufacture and skill in their application to the curtain. i j j `Our present invention has for itsaobject a the maintaining of` the/window curtain `in i any position in which it may be placed, and our invention consists in a peculiar form of i .socket upon which one end of the roller turns, which is made adjustable for the pur- `pose of graduating the` amount of pressure upontherodfto the weight of the curtain.` In the"accompanyingjdrawings B is the j rod to which the curtain `is attached,to` one `olle or center @,-this spindle runs in the socket D-which is secured to the window jambs by screwsorotherwise as seen vin Fig.

\ 1. Atthe other end` there is an adjustable ,i socketE, which` `is `made to` bear upon the `end of the rod in the following manner.

` j The `shank of this socket is bent from the perpendicular as seen in 1, and rests `against the windowgjamb at the point X, where it is conned by a screw ;-`-this socket is cup formed as seen inf Figs. 1 and 5, and

into the end of the latter by a blow or otherwise, by which means a circular depression ,CZ (Figs. 2` and 4) is formed in the end of the rod. i When the curtain is to be hung the socket D, being secured .to the jamb, the center a is placed in it, and the socket E is attached to the lopposite jamb and the screw f is sufficiently loosened to enable the center g within the groove cZ'to enter the cup 71, ofthe socket F, the screw f is then tightened "untilsuiiicient friction is produced between the socket androclto retain the latter in any position in which it may be placed.

The curtain may be removed when desired by loosening the screw f,-and by tight- Aeningthis screw the pressure upon the curj tain rod may be increased to any required amount, and the curtain may thus be held in any desired position without springs,

If the latter does not hang even, or it becomes necessary, at i any time to adjust its position upon therod it is `simply necessary to loosen ,one of the screwsin order to readjust it;

The peculiar method o-f balancing and supporting the window curtain by means of the adjustable socket E has many advantages, among which may be enumerated,

first, its extreme cheapness,the two sockets `replacing thebrackets heretofore required,

and at the same time performing everything before accomplished by the springs, weighted tassels and other contrivances employed; second, the same socket answers for curtains of an ysize and weight; third, it is exceedingly simple and not liable to get out of order.
